到目前为止我已经尝试过这个，但它给了我错误:注意:数组到字符串的转换"

I have tried this so far but it gives me error: "Notice: Array to string conversion in "

            {% for route in routes %}

            <p>
                {{ route.admin }}
            </p>

        {% endfor %}

推荐答案

为了读出一个完整的数组，您需要创建某种形式的递归.您可以使用

In order to read out a full array, you would to create some form of recursion. You could achieve this with a macro in the line of

macros.twig

{% macro readArray(array) %}
    {% import _self as macros %}
    {% if not array is iterable %}
        {{ array }}
    {% else %}
        {% for k,v in array %}
        <ul>
            <li>
            {{ k }}: {{ macros.readArray(v) }}
            </li>
        </ul>
        {% endfor %}
    {% endif %}
{% endmacro %}

main.twig

{% import "macros.twig" as macros %}

{{ macros.readArray(results) }}
